Why is the deletion of a DNA base likely to have more serious effects than a DNA base subsitution?
If a base is merely substituted, the reading frame remains altered only by that one base, which may or may not change the amino acid encoded in the codon. If a base were inserted or deleted, there will be a reading frame shift which would have a profound effect on the amino acids encoded.
For example, a sample of RNA has the following sequence:
AUG AUA AAG CUA CCG GGC UAG ...
which translates to M-I-K-L-P-G
If the second condon changed from AUA to AUC, then the amino acid sequence would remain the same.
If the second condon were to have its second A deleted, then the entire amino acid sequence changes to:
M-I-S-T-R-A...

Which of the following types of mutation resulting in an error in the mRNA just after the AUG start of translation is likely to have the most serious effect on the polypeptide product?
A frameshift mutation, such as an insertion or deletion of a nucleotide, that occurs just after the AUG start codon is likely to have the most serious effect on the polypeptide product. This is because frameshift mutations shift the reading frame of the mRNA sequence, causing all subsequent codons to be read incorrectly, leading to a completely altered polypeptide sequence.
What has most likely occured if a chromosome lacks certain genes?
If a chromosome lacks certain genes, it is likely due to a genetic mutation or deletion event that occurred during DNA replication or recombination. This can lead to genetic disorders or abnormalities depending on the specific genes that are missing.
How many amino acids are affected by a deletion of one nitrogen base?
A deletion of one nitrogen base would result in a frameshift mutation in the DNA sequence that codes for proteins. This would likely affect all amino acids downstream of the deletion site, leading to a significant alteration in the protein's primary sequence and possibly its function.
What small-scale mutation would be most likely to have a catastrophic effect on the functioning of a protein?
A single-nucleotide substitution causing a missense mutation that changes a critical amino acid in the protein's active site or functional domain is most likely to have a catastrophic effect on the protein's function. This type of mutation can disrupt the protein's structure or its ability to interact with other molecules, leading to severe functional impairment.
What kind of compound is most likely to mimic the effects of a hormone that influences sexual behavior?
A compound that is structurally and functionally similar to the hormone would be most likely to mimic its effects on sexual behavior. These compounds are called agonists and can bind to the hormone's receptor and trigger a similar response in the body.
Which of the following types of mutation resulting in an error in the mRNA just after the AUG start of translation is likely to have the most serious effect on the polypeptide product?
A frameshift mutation, such as an insertion or deletion of a nucleotide, that occurs just after the AUG start codon is likely to have the most serious effect on the polypeptide product. This is because frameshift mutations shift the reading frame of the mRNA sequence, causing all subsequent codons to be read incorrectly, leading to a completely altered polypeptide sequence.
What is the smallest change in DNA that causes a protein to change.?
A single change in the primary sequence of bases can result in complete misfolding of proteins. The most likely serious change would be addition or deletion of a base, a substitution would be less likey to be as serious but can also render a protein inactive.
What are three anomalies that are likely result to data redundancy?
The three types of anomalies likely to show up are: Insertion, Deletion, and Update anomalies.
What has most likely occured if a chromosome lacks certain genes?
If a chromosome lacks certain genes, it is likely due to a genetic mutation or deletion event that occurred during DNA replication or recombination. This can lead to genetic disorders or abnormalities depending on the specific genes that are missing.
The minimum dosage t?
The minimum dosage to be effective is 50mg, three times a day, morning around 8 am, 2pm and 9pm are the optimal times You would likely notice side effects within a week, but serious side effects are rare
The most serious effect of severe hypocalcemia is likely to be what?
The MOST serious effect would be death.
How many amino acids are affected by a deletion of one nitrogen base?
A deletion of one nitrogen base would result in a frameshift mutation in the DNA sequence that codes for proteins. This would likely affect all amino acids downstream of the deletion site, leading to a significant alteration in the protein's primary sequence and possibly its function.
People with what disease are most likely to have side effects from taking ondansetron?
People with liver disease may be more likely to have side effects from ondansetron.
What effects are the opening of CCC likely to have on Somewhere?
D
How do you spell seorious?
The likely word is the adjective serious (severe, or not humorous)
What are the effects of breast sucking on virgin lady?
She will likely enjoy it but just as likely remain a virgin
Can chlamydia remain in your fallopian tubes for years and then reoccur in your cervix?
Yes, but it would be very - very - VERY rare. Chlamydia does serious damage quick, so having it for "years" without having severe side effects is really not likely.
